[Dovecot] in a major jam... authentication
by tallison1 22 Jan '06

22 Jan '06

I was upgrading my debian box and managed to upgrade my dovecot installation at the same time. I wasn't planning on it, but it came along just the same. I took some notes on what I thought I needed to change, but apparently it wasn't enough. I've been running this for quite some time now with pgsql authentication and it's been one of those nice applications that always behave themselves. Until now. I can connect to the database. But I always fail the authentication. From the logs I'm coming in on a PLAIN authentication and failing on "password mismatch" The database hasn't changed the password in years. The database stores the password as (I believe) an md5 encryption of the real password. Whatever it is, it is definitely encrypted in the table. What I had in my configuration file was something like this: disable_plaintext_auth = no (this was marked as the default and I enforced it in the new file) auth_mechanisms = plain auth_passdb = pgsql:/etc/dovecot/dovecot-pgsql.conf auth_user = root login = imap I have updated the configuration as follows: dovecot-pgsql.conf 'driver = pgsql' 'default_pass_scheme = PLAIN-MD5' ( I tried changing this to PLAIN but it didn't help ) dovecot.conf protocols = imap disable_plaintext_auth = no protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } passdb sql { args = /etc/dovecot/dovecot-pgsql.conf } userdb passwd { } user = root } I'm not sure what to try now, all I know is that my IMAP server is just dead and I'm unable to get the authentication working again. I can't find much that says how to set this up again and am reluctant to just start trying stuff.

Hi everyone, This is my second try with dovecot, and still no luck. What I want is twig to work with dovecot on the localhost address . I need to authenticate through pam for real accounts and through pgsql for virtual ones. I just cant autenticate: logs are : imap-:login: Authenticate PLAIN failed: Unsupported authentication mechanism or: Aborted login: method = PLAIN Could someone please share a working config file that does what I want? I'm struggling for weeks now both on tyhe alpha5 and beta1 versions.

[Dovecot] INBOX as either mbox or Maildir
by Tom Alsberg 22 Jan '06

22 Jan '06

In Dovecot 0.99, I recall somewhere I read it was possible for INBOX to be both a Maildir and an mbox in the same configuration (either automatically detected, or depending on the existence in a different location). Perhaps I was wrong, I'm not sure. Any way, I now became interested in this sort of setup: Most users have their spool an mbox in /var/mail/<username>, and then they (or their MUA) have to move read mail from there to ~/mbox or something like that (a state in which users use the spool as a long-time storage space is unacceptable, and we have measures to avoid it). However, for those that will access their mail only via IMAP, it will be easier to set in .forward or something like that automatic delivery directly to their mailbox - some Maildir in their home directory (there can then be a link from /var/mail or /var/maildir or whatever to there), which will contain both read and new messages. In such a case one would want INBOX to be that main mailbox. Would it be possible to set Dovecot to either automatically detect whether /var/mail/<username> is a Maildir or mbox (which relates to my interest in mixing maildirs and mboxes in one namespace which I have written about several months ago) or to configure several options for INBOX with the first one found used?

This is what's happened: I had original made an rpm with checkinstall, so I removed the dovecot user, so that a new install would set it up with the expected UID and GID, and removed the rpm. My 'bright' idea was that I would install the official Fedora 0.99.14, then install 1.0bet1 over it. I had been assured earlier that it would install over the executables, so it seemed reasonable. I got 0.99.14 on, but could not find the dovecot.conf.example or dovecot.conf to check paths, which worried me a bit, so I thought that if I attempted a login it would give me errors that would define a path. For the first time ever, it logged in! What's more, I can see my imap directories on another box. The only dovecot.conf that I know about is the copy that was in /home/anne. What do you think is happening? If all is working I will leave well alone. This is to be a temporary mail server while I do an upgrade. I don't want to do any more work on it than I need to, because I will be doing it over again, for a permanent install, on the upgraded box in a week or so.

[Dovecot] beta1: assert due to hard fs quota
by Jeff A. Earickson 20 Jan '06

20 Jan '06

Hi, In the "for what it is worth" category... The following assert popped up in beta1 on Solaris 9 this morning: imap(user): file mail-index-view-sync.c: line 155 (view_sync_get_expunges): assertion failed: (ret == 0) The user had hit a hard disk quota on their home directory, ie where the indexes go. Dovecot cored with a zero-byte core file in the user's home directory, naturally. Jeff Earickson Colby College

[Dovecot] Login user doesn't exist: dovecot
by Anne Wilson 20 Jan '06

20 Jan '06

After completely trashing my system a few days ago, I now have FC4 running, and have compiled dovecot-1.-beta1. Everything is placed in a different place from the debian install, so it's possible that I have a path problem. Attempting to start dovecot in a root console brings up the line Login user doesn't exist: dovecot Advice, please? Anne

[Dovecot] Major CPU spike for SSL parameters?
by Todd Vierling 20 Jan '06

20 Jan '06

I went from a nightly of about 20051117 or so (about alpha4 generation) to 1.0beta1 yesterday, and dovecot is now spinning the CPU furiously apparently every ~10 minutes per: Jan 18 13:04:36 server dovecot: SSL parameters regeneration completed Jan 18 13:14:14 server dovecot: SSL parameters regeneration completed Jan 18 13:24:00 server dovecot: SSL parameters regeneration completed Jan 18 13:37:09 server dovecot: SSL parameters regeneration completed Jan 18 13:44:21 server dovecot: SSL parameters regeneration completed Jan 18 13:54:37 server dovecot: SSL parameters regeneration completed Jan 18 14:04:03 server dovecot: SSL parameters regeneration completed Jan 18 14:14:58 server dovecot: SSL parameters regeneration completed Jan 18 14:24:03 server dovecot: SSL parameters regeneration completed Jan 18 14:34:18 server dovecot: SSL parameters regeneration completed Jan 18 14:44:11 server dovecot: SSL parameters regeneration completed Jan 18 14:53:44 server dovecot: SSL parameters regeneration completed Jan 18 15:04:16 server dovecot: SSL parameters regeneration completed Jan 18 15:13:59 server dovecot: SSL parameters regeneration completed Jan 18 15:25:22 server dovecot: SSL parameters regeneration completed Jan 18 15:33:58 server dovecot: SSL parameters regeneration completed Jan 18 15:44:03 server dovecot: SSL parameters regeneration completed Jan 18 15:54:13 server dovecot: SSL parameters regeneration completed Note that this is not the DH parameter generation; that completed on the first run, as documented. This is impacting other processes on the machine, and it seems a bit of a radical change. Is the internal default meant to be this short...? I'm going to attempt to set "ssl_parameters_regenerate" explicitly, but I'd like to stick with builtin defaults wherever possible. (Perhaps this regeneration could also be made a little friendlier on the machine, by forking and using setpriority() to lower the CPU demand of this work from the default nice level of the main daemon.) -- -- Todd Vierling <tv(a)duh.org> <tv(a)pobox.com> <todd(a)vierling.name>

[Dovecot] beta1: how to use quota plugin???
by Jeff A. Earickson 20 Jan '06

20 Jan '06

Hi, After searching gmane.mail.imap.dovecot on the topic, and wiki.dovecot.org, I'm still clueless on how to use RFC 2087 quotas in dovecot with the quota plugin. How come no wiki doc? My setup: Solaris 9, mbox format. Both the filesystem for INBOXes (/var/mail) and the user's home directories have filesystem-based quotas imposed. For example: % quota -v joeblow Disk quotas for joeblow (uid 20737): Filesystem usage quota limit /export/home 955 298000 302400 (where indices and mail folders go) /var/mail 530 151200 204800 (where joeblow's INBOX lives) If joeblow connects via dovecot IMAP, I want our webmail code (horde/imp) to tell him his disk quotas to keep him out of trouble. Horde/Imp (2.2.5) has quota code that says it works with Courier imap. Dovecot is supposed to be Courier compatible. How do I get the quota info out of Dovecot and down to Horde/IMP?

[Dovecot] no inbox error?
by John Woodell 19 Jan '06

19 Jan '06

When a new user has no inbox (has not received a message), the box client shows an error dialog. Is there any way to surpress this... besides touching an empty inbox for all valid accounts?
